Abstract

La présente invention concerne un dispositif d'éclairage (1) comportant une source de rayonnement de pompage (2) pour émettre un rayonnement de pompage sous forme de faisceau de rayons (4), un élément luminophore (22) et un système de lentilles (3, 5) situé entre les deux précédents (2, 22); ledit système de lentilles comportant un foyer au niveau duquel est monté l'élément luminophore (22), une lentille (5) du système de lentilles (3, 5) présentant un moyen de diffusion (26) qui traverse le faisceau de rayons de pompage (4), ce qui a pour effet de l'élargir, de sorte à élargir le faisceau de rayons de pompage (4) d'un point focal (27) sur lequel l'élément luminophore arrive.
